Additive genetic variance is the portion of genetic variance that can be attributed to the additive effects of alleles, which directly impacts the heritability of a trait. It is crucial in predicting the response to selection in breeding programs, as it represents the genetic component that can be passed from parents to offspring.

Additive genetic variance

Genetic variance refers to the diversity of alleles and genotypes within a population, which contributes to the population's ability to adapt and evolve. It is a crucial component of evolutionary biology, influencing traits and fitness, and is driven by mechanisms such as mutation, recombination, and natural selection.

Breeding programs are systematic approaches to improve plant and animal species by selecting desirable traits and managing reproduction to enhance genetic qualities over generations. These programs play a crucial role in agriculture, conservation, and biotechnology by increasing productivity, resilience, and sustainability of species.
